TECHNICAL FIELD

The present disclosure relates to the field of jigsaw puzzleaccessories, and in particular to a board-carrying support device.

BACKGROUND

Jigsaw puzzle, as a game or teaching tool, has been quite popular sinceit was invented. It is not only due to the low cost of manufacturingjigsaw puzzle, but also because of the diverse puzzle patterns, variousnumbers of the puzzle pieces, and other adjustable variables of thejigsaw puzzle games, giving people more playability. In addition, as theliving standard continuously increases and the society develops day byday, the jigsaw puzzle is utilized as a hobby, besides of a puzzle gameor a preschool education tool. Because there are many jigsaw puzzlelovers, jigsaw puzzles with more patterns, various difficulties arepresent on the market, including double-sided puzzles, three-dimensionalpuzzles, and etc.

Currently, jigsaw puzzles are mostly made of cardboards, and the patternof the jigsaw is the pattern drawn on the surface of the cardboardbefore cutting. The painted cardboard is stamped by special machine toolto complete the manufacturing. As a result, the puzzle pieces withoutexternal adhesive are difficult to be connected with each other tightly.Therefore, during the process of a jigsaw game, the player usuallyprepares a support panel or a special table for placing the puzzlepieces. However, in the process of a jigsaw puzzle game, it is verylikely that the puzzle piece picked every time is not the puzzle pieceadjacent to the previously picked puzzle piece in terms of the patternof the puzzle. Therefore, the player has to drop several puzzle pieceson the desktop, usually rendering puzzle pieces placed on the corners ofthe desktop away from the player, and due to the flatness of thedesktop, the view angle of the player is difficult to focus on thepuzzle pieces located at the corner of the desktop in real time.Consequently, the player cannot comprehensively consider the pattern ofthe puzzle in an overall manner in the game process, which decreases theplayability of the game. Meanwhile, when some puzzle pieces are placedon the corner of the desktop far away from the player, it is difficultfor the player to reach and pick up the corresponding puzzle pieces,which will also significantly affect the game experience of the player.

SUMMARY OF THE DISCLOSURE

The present disclosure provides a board-carrying support device,including a support frame, a bearing board assembly, and a rotatingconnection member. A plane in which the support frame is located isdefined as a reference plane. The support frame and the bearing boardassembly are rotatably connected to each other through the rotatingconnection member, enabling the bearing board assembly to be rotatedbetween a first position and a second position. The first position andthe second position of the bearing board assembly are on a same side ofthe reference plane. The board-carrying support device further includesat least two reinforcing members connected to the support frame tosupport the support frame. When the bearing board assembly is rotated toreach the second position, an inclination angle between the bearingboard assembly and the reference plane is less than 90°.

DETAILED DESCRIPTION

In order to illustrate the purpose, technical solutions and advantagesof the present disclosure more clearly, each embodiment of the presentdisclosure will be described in detail below by referring to theaccompanying drawings. However, any ordinary skilled person in the artshall understand that many technical details are presented in theembodiments of the present disclosure in order to enable the reader tobetter understand the present disclosure. However, even without thesetechnical details and various variations and modifications based on thefollowing embodiments, the technical solution claimed by the presentdisclosure may still be achieved.

Embodiment I

As shown in FIG. 1 to FIG. 15 , the board-carrying support deviceincludes a support frame 1, a bearing board assembly 3, and a rotatingconnection member 5. The support frame 1 and the bearing board assembly3 are rotatably connected to each other through the rotating connectionmember 5, enabling the bearing board assembly 3 to be rotated between afirst position and a second position, such that an inclination angle ofthe bearing board surface 30 of the bearing board assembly 3 may change.In this way, the inclination angle of the bearing board assembly 3 maybe adapted to a viewing angle of the player of the jigsaw puzzle, andthe player may fully focus on the puzzle pieces located on the variouslocations of the bearing board assembly 3 and may easily reach and pickup the puzzle pieces located on the various locations of the bearingboard assembly 3 during playing the jigsaw puzzle. Therefore, the gameexperience of the player of the jigsaw puzzle may be enhanced, andattraction of the jigsaw puzzle to the player may be improved.

A plane in which the support frame 1 is located is defined as areference plane. The first position and the second position of thebearing board assembly 3 are located on a same side of the referenceplane. Further, when the bearing board assembly 3 is rotated to reachthe second position, the inclination angle between the bearing boardassembly 3 and the reference plane is less than 90°.

To be noted that, the first position of the bearing board assembly 3refers to a position, which is reached by the bearing board assembly 3being rotated, through a rotation shaft of the rotating connectionmember 5, and is parallel or almost parallel to the reference plane. Itwill be understood that, the first position is not limited to theposition, which is reached by the bearing board assembly 3 being rotatedand is parallel or almost parallel to the reference plane. For example,the first position may alternatively be a position, which is reached bythe bearing board assembly 3 being rotated and has a slight angle (suchas 1°, 2°, 3°, and so on) with respect to the reference plane.

The second position of the bearing board assembly 3 refers to aposition, which is reached by the bearing board assembly 3 being rotatedand has the inclination angle with respect to the reference plane. Insome embodiments, the inclination angle is less than 90°. In someembodiments, the inclination angle is set to be greater than or equal to10° and less than or equal to 60°. The inclination angle enables thebearing board assembly 3 to be adapted to carry the puzzle pieces and tobe adapted to the viewing point of the player. In this way, the playermay be provided with a better jigsaw puzzle playing experience, andplayability of the jigsaw puzzle may be improved, such that the viewingpoint of the player may be adapted, and a carrying capacity andstability of the bearing board assembly 3 carrying the puzzle pieces maybe improved.

The support frame 1 and the bearing board assembly 3 are hingedlyconnected to each other through the rotating connection member 5. Therotating connection member 5 may be a hinge. In other embodiments, therotating connection member 5 may also be a rotation shaft.

The support frame 1 includes a first side wall 11, a second side wall12, and a pair of third side walls 13. The first side wall 11 isconnected to the bearing board assembly 3 through the rotatingconnection member 5. The second side wall 12 is opposite to the firstside wall 11. One third side wall of the pair of third side walls 13 isconnected to the first side wall 11, and the other one third side wallof the pair of third side walls 13 is connected to the second side wall12. The one third side wall 13 is connected to an end of the first sidewall 11 through a screw, and the other one third side wall 13 isconnected to an end of the second side wall 12 through another screw.

The first side wall 11 may receive a heavy loading while the bearingboard assembly 3 is being rotating through the rotating connectionmember 5, and the bearing board assembly 3 and the support frame 1 areusually made of wood. Therefore, when the first side wall 11 of thesupport frame 1 connected to the rotating connection 5 member is alayering structure (such as laminated sheets), the loading is quiteclose to a support force applied by the side wall of the layeringstructure to the rotating connection member 5 (that is, the supportforce applied by the side wall of the layering structure to the rotatingconnection member 5 may be insufficient). Therefore, in the presentdisclosure, the first side wall 11 of the support frame 1 is a one-pieceand integral structure. That is, the first side wall 11 is a one-pieceof wood, and is not a laminated multi-layer wooden structure, such thatthe support force applied by the first side wall 11 of the support frame1 to the rotating connection member 5 is increased, and the service lifeof the device is increased.

In the present embodiment, the bearing board assembly 3 is hingedlyconnected to an inner side of the support frame 1. Further, when thebearing board assembly 3 is rotated to reach the first position, thebearing board assembly 3 is arranged inside the support frame 1. In thisway, when the board-carrying support device is not in use, the bearingboard assembly 3 may be folded to be completely received inside thesupport frame 1, such that the board-carrying support device is compactafter being folded and can be stored easily.

In the present embodiment, the first side wall 11 defines a first recess111 and a second recess 112 at a position opposite to the second sidewall 12, and the second side wall 12 also defines a first recess 111 anda second recess 112 at a position opposite to the first side wall 11.The first recess 111 is spaced apart from the second recess 112.

A middle board 16 is fixedly arranged inside the support frame 1. Acircumference of the middle board 16 is embedded in the first recess111, and the middle board 16 is connected to the third side wall 13,such that the middle board 16 is fixedly arranged inside the supportframe 1.

A plate surface of the middle board 16 is parallel to the referenceplane in order to limit rotation of the bearing board assembly 3. Inthis way, on one hand, structural stability of the board-carryingsupport device may be improved. On the other hand, an accommodationspace may be defined between the middle board 16 and the bearing boardassembly 3 to increase the storage capacity of the board-carryingsupport device. In particular, for example, a finished jigsaw puzzle maybe accommodated in the accommodation space, further increasingusefulness of the board-carrying support device.

It is worth mentioning that when the bearing board assembly 3 is rotatedto reach the first position, the bearing board assembly 3 is receivedinside the support frame 1. That is, a stacked state of the bearingboard assembly 3 and the middle board 16 is formed. In this way, a sizeof the board-carrying support device may be reduced, the board-carryingsupport device may be stored easily, and the board-carrying supportdevice may be transported and carried easily.

It is worth mentioning that in the present embodiment, the support frame1 is an enclosed frame to ensure the structural stability of the supportframe 1. To be understood that, in some embodiments of the presentdisclosure, the support frame 1 is not limited to be the enclosed frame.That is, the support frame 1 may be implemented as an opening frame,such as a structure formed by two frame bars fixed on a same plane, aslong as the support frame 1 defines a plane.

The bearing board assembly 3 includes a bearing board 31 and a bearingframe 33. The frame 33 is arranged around the bearing board 31 and isconnected to the rotating connection member 5. The frame 33 is arrangedwith a mounting portion 331, and the bearing board 31 is mounted in themounting portion 331.

The bearing board 31 and the frame 33 may be made of a same material ordifferent materials. In some embodiments, the bearing board 31 and theframe 33 have different expansion coefficients. An expansion coefficientof the frame 33 is lower than that of the bearing board 31, such that agreater support force is provided to ensure flatness of the bearingboard 31.

The mounting portion 331 includes a first mounting surface 333 and aretaining surface 335. The first mounting surface 333 is configured tomount the bearing board 31. The retaining surface 335 is opposite to aside edge of the bearing board 31. The retaining surface 335 isconnected with the first mounting surface 333.

It will be understood that in other embodiments, the mounting portion331 may include a second mounting surface 337 and the retaining surface335. The second mounting surface 337 is opposite to the first mountingsurface 333, and the retaining surface 335 is connected to the secondmounting surface 337. The first mounting surface 333, the secondmounting surface 337, and the retaining surface 335 cooperatively definea mounting slot to receive the side edge of the bearing board 31.

In the present embodiment, a gap 3A having a predetermined spacing isdefined between the retaining surface 335 and the bearing board 31. Thegap 3A provides a space for deformation of the bearing board 31 or/andthe frame 33. In this way, the bearing board assembly 3 may be preventedfrom being deformed caused by expansion of the bearing board 31 and theframe 33 and/or compression between the bearing board 31 and the frame33 due to an external force applied on the frame 33.

In the present embodiment, a friction pad 35 is arranged on a side ofthe bearing board assembly 3 away from the reference plane. The frictionpad 35 is configured to increase friction between the bearing boardassembly 3 and an object carried on the bearing board assembly 3. Inthis way, static friction between the bearing board assembly 3 of thebearing board assembly 3 and any puzzle piece carried on the bearingboard assembly 3 may be increased, such that the puzzle pieces placed onthe bearing board assembly 3 may be stabilized and may be prevented fromfalling apart due to external forces such as wind blowing. Inparticular, assembled puzzle pieces, while the jigsaw puzzle game isbeing performed, may be prevented from being scattered around due to thewind blowing, such that the progress of the game and the mood of theuser may not be affected, and the player may play the jigsaw puzzle gamemore comfortably and may have a better playing experience.

In particular, with the structure “the support frame 1 and the bearingboard assembly 3 are connected to each other through the rotatingconnection member 5, enabling the bearing board assembly 3 to be rotatedbetween the first position and the second position”, the bearing boardassembly 3 may be designed in various forms. For example, the bearingboard assembly 3 may be circular, polygonal, or irregularly shaped. Theshape of the bearing board assembly 3 may be determined based on demandsof various users. Especially, the shape of the bearing board assembly 3may be determined to be flexibly adapted to various shapes of puzzles.For example, the circular bearing board assembly 3 may be more adaptableto puzzles having an overall circular pattern.

In the present embodiment, the bearing board assembly 3 is rectangular,such that the entirety of the bearing board assembly 3 may carry thepuzzle pieces and meet the gamer's habit of placing and laying out thepuzzle pieces while the player is playing the jigsaw puzzle game.Specifically, the rectangular bearing board assembly 3 (rectangular orsquare) may be adapted to carry various shapes of puzzle, such as, butnot limited to, a jigsaw puzzle having an overall rectangular shape, ajigsaw puzzle having an overall circular shape, a jigsaw puzzle havingan overall polygonal shape, and so on. In this way, the bearing boardassembly 3 may be adapted to a wide range of jigsaw puzzles, theproduction and design costs and the purchasing and usage costs ofboard-carrying support device may be reduced, facilitating promotion andapplication of board-carrying support devices. In addition, therectangular bearing board assembly 3 may be easily rotated, theboard-carrying support device may be operated easily, and a better userexperience may be provided.

In the embodiments, the friction pad 35 covers the bearing board 31 andthe frame 33. Specifically, in a direction perpendicular to the bearingboard assembly 3, an edge of the friction pad 35 overlaps an outer edgeof the frame 33. Specifically, the friction pad 35 may be a fleece. Itwill be understood that in other embodiments, the fleece may also bereplaced with a friction pad made of a material having a greaterfrictional force, such as a rubber pad.

It will be understood that in other embodiments, the friction pad 35 maycover only the bearing board 31. Specifically, in the directionperpendicular to the bearing board assembly 3, the edge of the frictionpad 35 overlaps an edge of the bearing board 31. Alternatively, thefriction pad 35 may cover the bearing board 31 and a part of the frame33. That is, in the direction perpendicular to the bearing boardassembly 3, the edge of the friction pad 35 falls on the frame 33.

Further, a plurality of first reinforcement members 37 are connectedwith each other and are arranged inside the frame 33. The plurality offirst reinforcement members 37 are disposed on a side of the bearingboard 31 facing towards the support frame 1.

When the board-carrying support device is not in use,the upholding frame 8 is rotated to a collapse position. In this way,balance of the board-carrying support device is maintained. Inparticular, while the jigsaw puzzle game is being performed, since theupholding frame 8 is expanded, the board-carrying support device may beplaced in a balanced position, providing stable support for the puzzlepieces. In addition, the upholding frame 8 may be folded, facilitatingthe board-carrying support device to be stored, and increasingpracticality of the board-carrying support device.

The upholding frame 8 is arranged with two support legs 81 opposite toeach other. Each support leg 81 includes two support legs 81 that areparallel to each other and a balance bar 82 connected between the twosupport legs 81. Preferably, two balance bars 82 are arranged and areparallel to each other.

Preferably, the upholding frame 8 is configured to have a maximumexpanded angle. The maximum expanded angle is a maximum angle betweenthe upholding frame 8 and the reference plane. The maximum expandedangle is preferably greater than or equal to 90° and less than 180°. Inthis way, balance of the board-carrying support device can be optimallyensured, and that is, a support applied by the upholding frame 8 to thesupport frame 1 can be ensured. Therefore, the board-carrying supportdevice can be placed in a balanced position, the puzzle pieces may beprevented from being scattered around due to instability of theboard-carrying support device, such that the mood of the player of thejigsaw puzzles may not be affected, and a better puzzle playingexperience can be provided.

It should be noted that the first position of the upholding frame 8 is aposition, which is reached by the upholding frame 8 being rotated and isparallel or nearly parallel to the reference plane. It will beunderstood that the first position is not limited to the position, whichis reached by the upholding frame 8 being rotated and is parallel ornearly parallel to the reference plane. The first position may be aposition, which is reached by the upholding frame 8 being rotated andhas an angle of, such as, 3°, 5°, 8°, and so on, with respect to thereference plane.

The second position of the upholding frame 8 is a position, which isreached by the upholding frame 8 being rotated and has the maximumexpanded angle with respect to the reference plane.

The upholding frame 8 is rotatably connected to the inner side of thesupport frame 1. When the upholding frame 8 is rotated to the collapseposition, the upholding frame 8 is received inside the support frame 1,further facilitating the storage of the board-carrying support deviceand increasing the practicality of the board-carrying support device.

It is worth mentioning that, since both the bearing board assembly 3 andthe upholding frame 8 can be rotated to the respective collapsepositions and stored in the support frame 1, and since the storagecontainer 7 is allowed to be pushed into the accommodation opening 1Band is hiddenly received in the support frame 1, the board-carryingsupport device is allows to be folded into a form having a size of onlyone panel, such as the board-carrying support device in the foldedposition as shown in FIG. 1 and FIG. 2 . The board-carrying supportdevice is folded to a size of a frame surface of the support frame 1. Inthis way, a minimal area is occupied to store the board-carrying supportdevice. Therefore, the board-carrying support device may be storedflexibly, and the user may carry and transport the board-carryingsupport device easily.
